Netify Agent

Netify DPI - netifyd Agent

Managing modern networks requires insights at the application, protocol, security, and data intelligence layers. Netflow data is good, but DPI provides the metadata to take network and cybersecurity analysis to the next level. If you are looking for an open source deep packet inspection engine to integrate with your solution, then you have come to the right place. Our Netify DPI software has been integrated into firewalls, routers, SD-WAN solutions, IoT gateways, mobile core network engines, virtual probes, software-defined network architectures and other OEM devices.

Use Cases

Here are just a few examples of how Netify DPI is used around the world:

• Prioritizing network traffic based on application and modern protocols, not IP lists
• Pinpointing bottlenecks by application, e.g. Microsoft Teams response times
• Identifying malicious traffic, even when encrypted
• Creating application-level QoS/latency policies
• Generating latency-friendly routing policies in multiWAN/SD-WAN environments

How It Works

The open source Netify DPI Agent - netifyd - does one thing and one thing very well: network analysis using deep packet inspection (DPI). The DPI Agent passively captures network traffic and then produces network metadata and policies:

• Network Policies
• Data Streams
  - Detection Metadata
  - Stats and Performance Data
  - Status Data

Product Highlights

Netify agent highlights include:

The protocol detection is handled by a modified version of the nDPI library. Netify adds handling for run-time application definitions, network policies, JSON data streams, packet dynamics, packet pipelines, and more. The source code is ready to use on various popular Linux distributions, FreeBSD, OpenWRT, Raspberry Pi and more. If you're a technical guy, you can find all the source code on Netify's GitLab project page.
